'I always wanted to shoot Amitabh Bachchan running'

I love to picture him running -- he immortalised that on the poster of 1978's Don. It is an iconic poster and Amitji's running has also become iconic.

At the peak of his career, his running was never shot brilliantly because of the techniques available at that time.

I always wanted to shoot Amitabh running and I got the opportunity when I shot with him for his film Aladin (2009).

On the day of the shoot, I asked him whether I could shoot pictures of him running. He was not very confident about how I would capture it.

I just told him to run. I remember I kept a bunch of keys as a mark. He would come running 10-12 feet behind that marker and as he would reach it, I would start clicking. He did it three or four times. It was absolutely stunning.

He loved the picture so much, he posted it on his blog and also mentioned that it was fun shooting with me.

'He has got a rare collection of cameras'

I had bought a Leica camera, and knew that Amitji was an avid photographer.

I asked him to click a picture of the two of us in his vanity van. This is a very personal photograph.

His knowledge about lighting and camera of still photography is tremendous.

The Leica camera is a very difficult camera to operate. It is a manual camera, and it is difficult to manually focus it. Even a professional photographer may not be able to focus but Amitji was brilliant at it. He has got a rare collection of cameras.
